A projector including a projection section that projects image light, a power supply section that supplies the projection section with electric power, a first enclosure that accommodates the projection section, and a second enclosure that accommodates the power supply section, wherein the second enclosure is fixed to a ceiling joist receiver that serves as a support member that supports a ceiling plate that partitions a space into a living room space and a space behind a ceiling, and the first enclosure and the second enclosure are configured to be separate from each other.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A projector to be installed in a ceiling of a building having a hanging ceiling structure, the projector comprising: a projection section that projects image light, the projection section including a light source, a light modulator that modulates light emitted from the light source to produce the image light, and a projection system that projects the image light from the light modulator; a power supply section that supplies the projection section with electric power; a first enclosure that accommodates the projection section; and a second enclosure that accommodates the power supply section, wherein the second enclosure is configured to be fixed to a support member that is supported by a building frame of the building, the second enclosure is not fixed to the ceiling, the second enclosure is directly fixed to the support member, and the first enclosure is indirectly fixed to the support member via the second enclosure, a partitioning surface of the ceiling is configured to be support by the support member and to partition a space into a first space that is an indoor space of the building and a second space that is a space behind the ceiling of the building, the first enclosure and the second enclosure are configured to be separate from each other, at least part of the first enclosure is disposed in the second space such that a weight of the first enclosure on the first space is reduced, a projection port formed in the first enclosure is exposed through an opening provided in the partitioning surface, the projection section projects the image light through the projection port into the first space, and the first enclosure is fixed to the second enclosure.
2. The projector according to claim 1 , wherein a position on the second enclosure where the first enclosure is fixed thereto is allowed to be changed in a direction parallel to the partitioning surface.
3. The projector according to claim 1 , wherein a position of the first enclosure fixed to the second enclosure is allowed to be changed in a direction perpendicular to the partitioning surface.
4. The projector according to claim 1 , wherein the first space is an indoor space of a building.
5. The projector according to claim 1 , wherein the second space is above the ceiling, and the first space is below the ceiling.
